[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine, and more particularly to a slot machine which, when a medal is detected other than when a prize is paid out, judges that the medal is abnormal due to fraud or the like and informs the user of the medal. The abnormality is not notified by the medal forcibly paid out.

[0002]

2. Description of the Related Art Conventionally, as a slot machine of this kind,
In addition to paying out a predetermined number of bonus medals according to the prize mode while monitoring the medals actually paid out at the time of prize, in addition to at the time of prize, the internal medals are forcibly checked for operation and medal collection etc. In addition to paying out, when a medal is detected other than at the time of winning payout, it is determined that there is an abnormality such as a device failure or improperity, and in order to notify this, for example, an error display or a buzzer is sounded. Slot machines are known.

Hereinafter, this conventional slot machine will be described with reference to FIG.
And will be described. Here, FIG. 9 is a block diagram showing medal payout control of a conventional slot machine, and FIG. 10 is an operation timing chart of the conventional slot machine. In FIG. 10, (a) shows the time when a prize is paid out, (b) shows abnormal stop 1 at the time of forced payout,
(C) shows an abnormal stop 2 during forced payout, and (d) shows an abnormal stop 3 during forced payout.

[0004] The conventional slot machine illustrated in FIG.
A prize judging means 200 for judging a prize during the game and outputting a prize signal indicating a predetermined number of medals according to the prize mode, a payout device 210 for paying out medals by a built-in motor 211, and this payout A drive circuit 220 that drives the device 210, a medal sensor 230 that detects a medal paid out from the payout device 210 and generates a medal detection signal,
The medal detection signal from the medal sensor 230 and the prize signal from the prize determination means 200 are input, respectively, and a payout signal is output on condition that the prize signal is input, and the medal is detected based on the input prize signal and the medal detection signal. A payout control means 240 for stopping the output of the payout signal on condition that the number of medals detected by the sensor 230 has reached the number of bonus medals, and a collection signal for operating at the time of collection and forcibly paying out medals is generated. And a recovery switch 250 for performing the operation. The collection switch 250 and the medal sensor 230
Generates an active "L" signal during operation,
The opposite output sides are each grounded.

In the input stage of the drive circuit 220, as shown in FIG. 9, an active coil switch 221 at an input signal level "L" is inserted in the drive circuit 220. Specifically, the coil switch 221 has one end of a built-in coil (not shown) pulled up by a positive power supply, and the other end connected so that a payout signal from the payout control means 240 and a recovery signal from the recovery switch 250 can be input. ing. Then, at the time of inputting the recovery signal or the payout signal, the coil switch 221
While the "L" signal is being input without distinction of which signal has been input, a current flows through the coil and the coil is energized to perform a switch operation, connect the interrupted drive circuit 220 and connect the payout device 210 Is operated.

Further, as shown in FIG. 9, the slot machine receives a payout signal from the payout control means 240 and a medal detection signal from the medal sensor 230, and receives a medal while the payout signal is not input. When the detection signal is input, it is determined that there has been an irregularity or the like, and an abnormality determination unit 260 that outputs an alarm signal for notifying an abnormality, and an alarm signal from the abnormality determination unit 260 is input, and the abnormality is determined. An alarm means 270 for notifying is provided, and when a medal detection signal, that is, an "L" signal is detected except at the time of winning and payout, an abnormality is notified.

The medal payout at the time of winning in the conventional slot machine configured as described above will be described. First, the winning determination means 200 determines this winning and a payout signal is output from the payout control means 240. . The payout of medals is started by turning on the payout signal. As shown in FIG. 10A, a pulse-shaped medal detection signal is output from the medal sensor 230 which has detected the paid-out medals.
Immediately after obtaining 3 pulses), the payout signal is turned off. If a medal detection signal, that is, an "L" signal is detected other than between the ON and OFF states of the payout signal, it is determined that this is due to a device failure or improper operation. Note that the payout signal is
Since a certain time is required from F to the motor 211 completely stopping, if the medal payout interval is short, the motor 211
In some cases, medals may be paid out due to the inertia of the motor.
The payout interval of medals is determined in consideration of the stop time of 1.

[0008]

However, in this conventional slot machine, an abnormality is determined by a medal detection signal obtained other than at the time of output of the payout signal as described above. All the medals given out were judged to be abnormal. And for a game store, not only is it necessary to perform collection while the abnormality is reported, but also at each collection, it is necessary to release the abnormality report, and if the abnormality report is due to fraud, etc. Had to be distinguished.

In order to cope with this problem, there is a method of simply turning off the medal detection signal while the recovery switch is operating. However, there are some problems described below depending on the timing at which the recovery switch is turned off. In some cases, the anomaly notification is sometimes made or not, so it is confusing, and this method has not been adopted. That is, FIG.
In the case of the payout of 0 (a), the payout signal is turned off immediately after the last pulse is obtained, and the OFF timing is controlled.
Since the timing of cutting off may be artificially and greatly fluctuated, it may deviate from immediately after the last pulse as shown in FIG. 10 (b). If the next medal has already been taken in at that time, then the motor 211 A first problem such as the medal being paid out by inertia (abnormal stop 1) may occur.

[0010] In some cases, there is a second problem that the recovery switch is turned off in the middle of the pulse as shown in FIG. 1C (abnormal stop 2). Further, as shown in FIG. 10D, the motor may stop during the output of the medal detection signal of the medal paid out by the inertia of the motor after the collection switch is turned off.
In this case, a third problem may occur in that the medal detection signal remains out of the medal sensor. Then, when these abnormal stops 1 to 3 occur, a medal detection signal of signal level "L" is detected after the collection signal is turned off, so that an abnormality is reported in any case.

Therefore, the first aspect of the present invention is to solve the first and second problems described above, and an object of the present invention is to turn off the medal detection signal while the collection switch is operating. In such a case, it is an object of the present invention to provide a slot machine capable of preventing an abnormality from being notified by a forcibly paid out medal, such as a medal collection, at a timing when a collection switch is turned off.

[0012] The invention according to claim 2 has, in addition to the object of the invention according to claim 1, a medal switch, a recovery switch, a coil switch, and the like for simplifying the slot machine according to claim 1. Are activated at the signal level "L" so as not to hinder the medal payout operation at the time of winning. That is,
When this signal level is activated at "L" and the payout signal from the payout control means sometimes reaches the input side of the delay circuit, this payout signal cannot be distinguished from the recovery signal, so that the payout signal is The cut-off means may be operated, and the medal detection signal may be cut off even when winning a prize. As a result, even though bonus medals are paid out one after another, a situation may occur in which the bonus medals cannot be counted and the payout signal is not stopped forever. The invention described in claim 2 is intended to prevent such a situation.

[0013] The invention described in claim 3 has the object of the invention described in claim 1 or 2 and the third aspect.
This is also intended to solve the problem described above, and aims to more reliably prevent abnormal notification at the time of forced payout by forcibly operating the payout device until the last medal is paid out.

[0014]

SUMMARY OF THE INVENTION The present invention is to achieve the above-mentioned object, and its contents will be described below with reference to embodiments shown in the drawings. In the invention according to claim 1, a collection signal from the collection switch (41) is input between the medal sensor (33), the payout control means (60), and the collection switch (41), and the start timing is delayed. The delay circuit (80) that outputs the end timing after delaying the end timing by a predetermined time without performing the operation, the recovered signal after the delay from the delay circuit (80) and the medal detection signal from the medal sensor (33) are respectively output. A signal cut-off means for inputting and interrupting the medal detection signal while the delayed recovery signal is being input, and outputting the medal detection signal to the payout control means (60) while the delayed recovery signal is not being input. (90).

According to a second aspect of the present invention, there is provided a recovery switch (41).
And between the drive circuit (70), in the middle of the connection,
A reverse signal for transmitting the recovery signal from the recovery switch (41) to the drive circuit (70) side, while preventing the payment signal from the payment control means (60) from going to the input side of the delay circuit (80). A blocking means (110) is provided. The invention according to claim 3 is characterized in that the signal cutoff means (90) connects the medal detection signal from the medal sensor (33) to the input side of the delay circuit (80) when the signal is cut off. .

[0016]

[Operation] Therefore, according to the first aspect of the present invention,
When the recovery switch (41) is turned on during the forcible payout of medals for recovery or the like, a recovery signal is sent to the drive circuit (70) and the delay circuit (80), respectively. The drive circuit (70) to which the recovery signal has been input drives the payout device (30) at the next stage while the recovery signal is being input, and forcibly pays out the internal medals.

On the other hand, from the delay circuit (80) to which the recovery signal is input, the recovery signal is output to the signal cutoff means (90) without delaying the start timing. After inputting the recovery signal, the signal blocking means (90) blocks the medal detection signal from the medal sensor (33) after inputting the recovery signal and does not output the signal. Thereafter, when the collection switch (41) is turned off, the output collection signal ends. Thereby, the dispensing device (30)
Stops and compulsory payout of medals ends,
When the end timing of the collection signal is delayed by a predetermined time by the delay circuit (80), the signal blocking unit (90) that has blocked the medal detection signal from the medal sensor (33) turns the collection switch (41) on. The cutoff is released after the cutoff timing.

On the other hand, at the time of a prize during a game, a prize signal from the prize determination means (50) is sent to the payout control means (60), whereby the payout signal is sent from the payout control means (60) to the driving circuit ( 70). Drive circuit (70) to which the payout signal is input
While the payout signal is being input, the payout device (3
0) is driven and the internal medals are forcibly paid out.

A medal sensor (33) that has detected the paid-out medals outputs a medal detection signal. The medal detection signal is sent to the payout control means (6) through a signal cutoff means (90).
Sent to 0). Payout control means that receives a medal detection signal
(60), based on the medal detection signal and the previously entered winning signal, stops outputting the payout signal on condition that the number of paid out medals has reached the number of bonus medals indicated by the winning signal. . That is, the payout of the medal ends when the payout device (30) has paid out a predetermined number of medals.

No payout signal is generated except at the time of forced payout of medals or at the time of winning payout. At this time, if a medal due to fraud is detected by the medal sensor (33),
A medal detection signal from the medal sensor (33) is used to determine the abnormality.
Although sent to (120), since the abnormality determination means (120) has not obtained the payout signal, it determines that this medal detection signal is due to fraud or the like. Then, an alarm signal is sent from the abnormality determining means (120) to the next alarming means (130), and the alarming means (130) notifies the abnormality.

In addition, according to the second aspect of the present invention, when the recovery switch (41) is turned on during the forcible payout of medals, the recovery signal is transmitted to the driving circuit (110) via the reverse signal blocking means (110). 70). On the other hand, at the time of winning payout, a payout signal is sent from the payout control means (60) to the drive circuit (70), and at this time, the payout signal traces the input path of the collection signal in reverse to the input of the delay circuit (80). Even if it tries to go to the side, it is not blocked by the reverse signal blocking means (110) on the way and is not input to the delay circuit (80).

According to the third aspect of the present invention, the medal detection signal interrupted by the signal interrupting means (90) at the time of forcible payout is transmitted to the delay circuit (80) via the signal interrupting means (90). The signal cut-off means (90) is sent to the input side and operates not only with the recovery signal but also with the medal detection signal.

And a medal sensor that is fixed in the middle of the medal payout path of the medal around the disk and detects the paid out medal and outputs a pulse-shaped medal detection signal in accordance with the following.
33, for example, including a microswitch and a photosensor.

The medal sensor 33, as shown in FIGS. 1 and 3, generates an active "L" signal at the time of operation. As shown in FIG. 2, on the front surface of the power supply unit 40, there is provided a collection switch 41 which is operated at the time of forcible payout of medals such as collection and generates a collection signal. This recovery switch 41 is also shown in FIG.
As shown in FIGS. 3 to 3, the opposite output side is grounded similarly to the medal sensor 33 described above.

In addition, inside this slot machine, FIG.
As shown in the figure, a prize is determined during the game, a prize determination means 50 for outputting a prize signal indicating a predetermined number of bonus medals according to the prize mode, a prize signal from the prize determination means 50 and Each medal detection signal from the medal sensor 33 is input, a payout signal is output on condition that the winning signal is input, and the number of medals detected by the medal sensor 33 is awarded based on the input winning signal and the medal detection signal. A payout control means 60 for stopping the output of the payout signal on condition that the number of medals has been reached, and a payout signal from the payout control means 60 and a collection signal from the collection switch 41 are input,
While the payout signal or the collection signal is being input, the motor
A drive circuit that supplies power to 32 and drives the dispensing device 30
70 and.

As shown in FIGS. 1 and 3, a recovery signal from the recovery switch 41 is input between the medal sensor 33, the recovery switch 41, and the payout control means 60, and the start timing thereof is delayed. Without delaying the end timing by a predetermined time, and then outputting a delay signal from the delay circuit 80 and a signal from the delay circuit 80 and a medal sensor.
Signal cutoff that inputs the medal detection signal from 33, shuts off the medal detection signal while the delayed recovery signal is input, and outputs the medal detection signal while the delayed recovery signal is not input Means 90 and a counter 100 which counts the number of pulses of the medal detection signal from the signal blocking means 90 and outputs it to the payout control means 60, and is reset by the next winning signal from the winning determination means 50. Have been.

As shown in FIGS. 1 and 3, between the recovery switch 41 and the drive circuit 70, the reverse signal blocking means 11 is provided.
0, for example, a diode is connected to the recovery switch 41 and the drive circuit 70.
Is inserted in the middle of the connection. This diode 110
Transmits the collection signal generated by the collection switch 41 to the drive circuit 70 at the time of forced payout such as collection, while the payout signal output from the payout control means 60 goes to the input side of the delay circuit 80 at the time of winning payout. It is to prevent it from happening.

The signal cut-off means 90 comprises, for example, a first coil switch operated by an "L" signal. Specifically, the first
As shown in FIG. 3, one end of a built-in coil of the coil switch 90 is pulled up by a positive power supply, and the other end thereof is connected so that a recovered signal after delay from the delay circuit 80 can be inputted. Then, the first coil switch 90 performs the switch operation by the current flowing through the coil and being excited during the input because the recovery signal as the input signal is active at the signal level “L” as described above. Thus, the path of the medal detection signal from the medal sensor 33 is interrupted halfway.

As shown in FIG. 3, the input stage of the drive circuit 70 has a second coil switch 71 which is activated by an "L" signal.
However, it is inserted in the middle of the drive circuit 70. Similarly to the first coil switch 90, the second coil switch 71 has one end of the coil pulled up, and the other end thereof includes the payout control means.
The payout signal from 60 and the collection signal from the collection switch 41 are connected so that they can be input. When the recovery signal or the payout signal is input, the second coil switch 71 excites the coil while the "L" signal is being input regardless of which signal has been input, and disconnects the drive circuit that has been cut off. 70
Is connected, power is supplied to the motor 32 of the dispensing device 30 to operate the dispensing device 30.

As shown in FIG. 1, the payout signal from the payout control means 60 and the medal detection signal from the medal sensor 33 are input to the slot machine, and the medal is detected while the payout signal is not input. When the detection signal is input, it is determined that there is improperity or the like, and an abnormality determination unit 120 that outputs an alarm signal for notifying the abnormality, and an alarm signal from the abnormality determination unit 120 is input, and the abnormality is determined. An alarm means 130 for informing is provided, and when a medal detection signal, that is, an "L" signal is detected other than at the time of payout of a prize, for example, an abnormality is displayed or an abnormality is notified by sounding a buzzer. .

With respect to the medal payout control of the slot machine configured as described above, the symbol V1
To V5, and will be described below with reference to the block diagram of FIG. 1 and the operation timing charts of FIGS. First, the medal payout at the time of winning during the game will be described. In the initial state where there is no winning, as shown in FIG. 4, the input V1 of the second coil switch 71 of FIG. 3 is held at "H" by pull-up at one end of the built-in coil. The input V2 of the delayed circuit 80 is also "H", and the output V3 of the delay circuit 80 is also "H". Also,
Since the first coil switch 90 is connected and there is no payout of medals, the output V4 of the medal sensor 33 and the output V5 of the first coil switch 90 are both "H".

If there is any fraud in this state, the medal sensor 33
Operates, and its output V4 is changed from "H" to
The abnormality determination means that inputs this when it becomes "L"
Since the payout signal 120 has not yet been obtained, it is determined that there is a fraud, and an alarm signal is output to notify the abnormality. If there is a prize during the game, a prize signal is outputted from the prize determining means 50 of FIG. Then, the counter 100 is reset, and a payout signal is output from the payout control means 60.
As shown in (a), the second coil switch input V1 becomes "H" →
The value then falls to "L", whereby the second coil switch 71 operates to start the motor 32 in the dispensing device 30. Since the potential drop of the second coil switch input V1 due to the payout signal is blocked by the diode 110 and is not transmitted to the input side of the delay circuit 80, as shown in FIGS. 4B and 4C, The delay circuit input V2 and the output V3 remain at "H".

By starting the motor 32, the dispensing device 30
, The medals are paid out one by one, and in response, the medal sensor 33 outputs a pulse-shaped medal detection signal as shown in FIG. This medal detection signal is
As shown in FIG. 9E, the output is output from the output V5 of the first coil switch 90 in the connected state, and is counted by the counter 100 in FIG.

Payout control means 60 receiving the medal detection signal
Compares the number of pulses of the medal detection signal with a predetermined number of bonus medals indicated by the previously inputted winning signal, and stops outputting the payout signal on condition that the number of paid out medals has reached the number of bonus medals. . Specifically, the medal sensor 33 is
Immediately after outputting the number of bonus medals (three in the figure) as shown in (e), the second coil switch output V1 is returned from "L" to "H" as shown in FIG. It is. As a result, the drive circuit 70 is again shut off and power is not supplied to the motor 32, but the motor 32 cannot be stopped immediately due to the inertia of the disk fixed to its drive shaft, After rotating by a predetermined time after the payout signal is turned off, the motor stops at the position indicated by the broken line in FIG.

Next, forced payout at the time of medal collection will be described with reference to FIGS. When the recovery switch 41 is turned on, a recovery signal is generated and the delay circuit input V2 is
As shown in FIG. 7B, the initial level is reduced from “H” to “L”. This recovered signal is output from the diode 110 of FIG.
Is also transmitted to the second coil switch input V1 side.

On the other hand, the delay circuit 80 which has received the recovery signal changes its output V3 from "H" to "L" at the start timing of the recovery signal, as shown in FIGS. The one-coil switch 90 is operated to cut off a medal detection signal from the medal sensor 33 that is input thereafter. As a result, the first coil switch output V5 remains at "H" as shown in FIG. The medal sensor output V4 is connected to the delay circuit input V2 when the first coil switch 90 is shut off as shown in FIG.
As shown in (d), the potential of the delay circuit input V2 remains at "L" upon detection of the first medal.

Thereafter, when the collection switch 41 is turned off, if the OFF timing comes immediately after the last medal detection signal as in the case of the prize, the motor 32 stops without any problem. Because of artificial and large variations, the last pulse may be delayed as shown in FIG. 5, and the next pulse may be output before the motor 32 stops (abnormal stop 1 in the conventional example). There is also a case where the last pulse is in the middle as shown in FIG. 6 (abnormal stop 2 in the conventional example). Also, as shown in FIG. 7, the motor 32 may stop during the output of the next pulse even further after the case of FIG. 5 (abnormal stop 3 in the related art).

In the case of FIG. 5 in which the next pulse is output until the motor stops, the second coil switch input V1 is set to the recovery switch 41 OFF by pulling up one end of the built-in coil.
At the same time, it is returned to the initial level "H", and accordingly, the delay circuit input V2 also returns to "H". After that, when a medal already taken in is detected by the inertia of the motor 32,
As shown in FIG. 5C, the delay circuit input V2 is supplied to the medal sensor output V4 by the first coil switch 90 in the cut-off state.
, It varies with the medal sensor output V4. As a result, the delay circuit input V2 starts a new delay time before the delay time once started at the OFF timing of the recovery switch 41 does not end,
In other words, the start of the delay time is postponed until the detection of the medals to be paid out after the OFF timing of the collection switch 41 ends. Therefore, the release of the first coil switch 90 is delayed by an amount corresponding to the delay of the start of the delay time. At this time, after the delay time has elapsed since the last medal has already been detected, the first coil switch output V5 remains consistently at "H" and does not drop to "L". The means 130 does not operate.

In the case of FIG. 6 in which the recovery switch 41 is turned off in the middle of the pulse, the second coil switch input V1 is set in the same manner as in FIG. Is returned to the initial level "H" at the end of the recovery signal, and accordingly, the delay circuit input V2 also tries to return to "H". However, since the delay circuit input V2 side is connected to the medal sensor output V4 by the cut-off first coil switch 90, it is forcibly held at "L" until the medal detection is completed. Therefore, the delay circuit input V2
5 (a), and the second coil switch input V1
As shown by the solid line in (b), the signal becomes “H” slightly after the OFF timing of the collection switch 41.

Due to the delay of the end timing of the recovery signal at the delay circuit input V2, the delay circuit output V3 also delays the start of the predetermined delay time by a certain amount of time, and therefore slightly delays the release of the cut-off state of the first coil switch 90. Becomes In the case of FIG. 7 in which the motor 32 stops during the output of the last pulse, the delay time does not start until the end of the last medal detection. Release of the cutoff state is delayed. Therefore, the motor 32 does not stop during the output of the pulse unlike the abnormal stop 3 of the conventional example.

In the above description, the second coil switch 71 is used to cut off and connect the drive circuit 70.
Not limited to this, for example, a triac as an AC control element
72 into the drive circuit 70.
Can be controlled by a trigger signal from the phototriac coupler 73 that operates based on the payout signal from the payout control means 60.

More specifically, as shown in FIG. 8, a buffer amplifier 74 amplifies the payout signal from the payout control means 60.
And a triac 72 inserted in the middle of the drive circuit 70, and a photo triac coupler 73 inserted between the triac 72 and the buffer amplifier 74 and having a pair of light emitting diodes 75 and another triac 76 built therein. You. The photodiode 75 in the phototriac coupler 73 has an anode connected to the power supply side of which the resistance is divided, and a cathode connected to be able to input the amplified output signal from the buffer amplifier 74. The other triacs 76 in the phototriac coupler 73 are connected to the drive circuit 70.
Are connected in parallel between the gate and the non-gate side terminal of the triac 72 inserted in the first stage. And the buffer amplifier 74
Triggered by light emitted from the light emitting diode 75 emitted by the payout signal amplified by the other triac
When the 76 turns on, a trigger signal is supplied to the triac 72 inserted into the drive circuit 70, and the triac 72 connects and disconnects the drive circuit 70 by the trigger signal, thereby controlling the supply of AC power to the motor 32. It is what you do.

Since the present invention is configured as described above, it has the following effects. Claim 1
According to the invention described above, when the medal detection signal is turned off during the operation of the collection switch, the abnormality is notified by the timing at which the collection switch is turned off, such as a medal that is forcibly paid out such as a medal collection. Can be provided.

That is, the medal detection signal is not output from the first coil switch until a predetermined delay time started by turning off the recovery switch has elapsed, so that the stop time of the motor used and the payout interval of the medal are taken into consideration. ,
If the delay circuit is configured to have a sufficient delay time,
A slot machine in which an abnormality is not notified by a compulsory payout medal can be provided.

In addition, according to the second aspect of the present invention, in order to simplify the slot machine of the first aspect, the medal switch, the recovery switch, and the coil switch are all activated at the signal level "L". In this case, the payout signal is prevented from being input to the delay circuit by the reverse signal blocking means, so that a situation in which the medal payout operation does not stop forever at the time of winning as described above can be prevented.

In addition, according to the third aspect of the present invention, by forcibly operating the payout device until the last medal is paid out, it is possible to more reliably prevent the abnormal notification at the time of the forced payout. That is, including the cases of FIGS. 5 to 7 of the embodiment, the collection switch is
Regardless of the timing, the start of the delay time of the delay circuit is delayed until the last medal detection is completed.
Since the interruption of the interruption state of the signal interruption unit always comes after the last medal detection in principle, the abnormality notification can be prevented more reliably without depending much on the medal payout interval or the motor stop time.
